GRASS OR GRAIN CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 708,556, dated September 9, 1902. vApplication filed January 6,1902. Serial No. 88,948. (Ne model.)

T cir/ZZ whom, it may concern:

Beit known that I, RAY WV. HUssEY, of Pendleton, county of Madison, and State of Indiana, have invented a certain new and useful Grass or Grain Cutting Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention relates to improvements in grass and grain cutting machines of the type shown in my former patent, No. 666,055, dated January 15, 1901.

The full nature of this invention will be understood from the accompanying drawings and the following description land claims.

In the drawings, Figure lis a plan view of the machine with the knife and finger-bar in a horizontal position and partly broken away and the tongue and doubletree broken away. Fig. 2 is an elevation of the side of the machine which carries the knife, the knife and fingerbar being in section and the tongue broken away and the doubletree omitted. Fig. 3 is a plan view of a portion of the knife, iingerbar, shoe, and connecting mechanism. Fig.

4 is a longitudinal Vertical section of the knife-head and its connection with the crank- Wheel for driving it, said wheel being in elevation. Fig. 5 is a` plan View of the bearingblock in the knife-head. Fig.A 6 is a horizontal section of the means formounting and controlling the knife and finger-bar. Fig. 7 is a central longitudinal section of a portion of the tongue and lneans for mounting the doubletree.

A pair of ground-wheels 10 carry an axle ll. Two frames are mounted on this axle. One of these frames consists of an oblique bar 12, secured at one end to the bar 13, to which the tongue 14 is bolted. The sleeves 15 and 16 are parts of this frame, being connected with bars 12 and 13, and t on the The other frame consists of an oblique bar 17, having at one `end the sleeve 18 on the axle 41l and secured aty its other end to the bar 19, which at one end is likewise mounted loosely on the axle. The seat 20 is supported on the spring 2l, that is bolted to a projection from the sleeve 16. A sprocket- Wheel 22 is looselymounted` on the axle 11, and a union between the axle and sprocketwheel is effected by the clutch mechanism 23. This clutch is made in the usual way, and the details need not here be explained.

AThe secondr frame described` rests under the and controlling the knife and finger-bar. The

forward end of this lower frame is connected by the spring 24 with a block 25, that carries the doubletree 26. The block 25 is slidably mounted on the bar 27 beneath the tongue and is held from rearward escape by the stop 28, which is secured to bar 27. In the front end of the lower frame there is a sleeve 3.0, (shown best in Fig. 6,) that forms a bearing for a hollow shaft 3l, and a shaft 32 is mounted within said hollow shaft. Said shaft 32 carries on its inner end a sprocket-wheel 33, to which power is transmitted by the chain 34, whereby the knife is driven. A beveled gear 35 is secured to the outer end of the shaft 32 and meshes with another beveled gear 36, that is secured on the shaft 37, mounted in the arms 38, extending 'oppositely from the hollow shaft 31. The shaft 37 extends at a right angle to the shaft 32, and the axis of one of said shafts would intersect the axis of the other if extended. Said shaft 37 carries a crank-wheel 39, with the crank-pin 40 thereon, which directly actuates thel knife. The lliverging arms 38 extend from the hollow shaft 31 and have bearing-sleeves 41, that are mounted in the posts 42 and 43, that extend upward from the shoe 44. The finger-bar 45 is secured to said shoe. The ngers 46 are secured to the finger-bar, and on them the knife-bar 47, with the blades 48 secured thereto, is mounted and reciprocates.

The knife-head 50 has a vertical slot in it for the vertical movement of the bearingblock 51, in which the crank-pin 40 from the crank-wheel 39 fits and operates, as shown in Fig. 4. This vertical slot for the bearingblock is formed by a stationary arm 52, that is a part of the knife-head, and the adjustable bar 53, held by the cap-screws 514 in a position opposite the stationary arm 52. The bearing-block is recessed at` each end, as

shown in Fig. 5, and the arm 52 iits in one re- IOO Athe bearing-block is held from escape.

cess,while the bar 53 fits in the other, whereby One cap-screw 54, that holds the bar 53, extends through the arm 55, forming a part of the knife-head, and the other cap-screw through a supplementary plate 56, that is Secured t0 the arm 55 by the cap-screw 57. The upper end of the plate 56 is secured to the upper end of the arm 52. With this arrangement the position of the bar 53 is rendered adjustable, and therefore the dimensions of the slot for the bearing-block 5l may be modified to accommodate said block with exactness and to take up any wear. With this construction by removing cap-screw 57 the knife may be readily removed when desired.

The bearing-block 51 contains an oil-chamber 60, with outlets 6l therefrom downward to the bearing-surfaces of said block and the knife-head and the outlet 62 to the crank-pin 40. This oiling apparatus is a prominent feature of this invention, inasmuch as it is a practical oiling means where the knife is driven as herein set forth.

In this type of machine the knife operates while the finger-bar is in any position to which it may be possible to move it. It may be folded upward or downward or it may be tilted or rocked forward or backward without affecting the operation of the knife. The knife, finger-bar, and mechanism for supporting and controlling the same are elevated by the lever 70, that is secured to the casting 7l, which is pivoted at 72 to the plate 73, that is secured on the inner side of the tongue. Said casting has an arm 74 extending forward at a right angle therefrom, which is reinforced by the brace 75. A link 76 extends from the outer end of the arm 74 and is pivotally connected with the frame-bar 19. By throwing the lever backward the frame-bar 19 will be elevated, and thereby the knife and fingerbar elevated. The plate 73 has a rack on its upper edge that is engaged bya suitable bolt 77 for holding the lever 70 in place. The weight of the knife, finger-bar, and the means for supporting and controlling the same is considerable, and to counteract it to some extent I provide an adjustable spring 78, that extends along the side of the tongue and is at its rear end attached to the bar 79, which is pivotally connected to thelower end of the casting 7l. The other end of the spring is connected with the threaded bolt 80, that extends through a bracket S1 on the side of the tongue and is held by the nut 82. By means of this nut the tension of said spring may be adjusted so as to greatly aid the lever 70 while elevating the parts above mentioned. This spring 78 also tends to lighten the weight on the shoe 44 during the operation of the machine. The spring 24 also cooperates with the spring 7S in the matter of lessening the weight of these parts and in elevating them during the draft of the team and causes the shoe to pass over the ground lightly. The knife and finger-bar are rocked forward or rearward by the lever 85, which is pivotally mounted on the axle beside the plate 86, and the connecting-rod 87 extends therefrom to the crank 88 on the sleeve 89, that is secured rigidly on the hollow shaft 31. When said lever S5 is drawn backward or pushed forward,the shoe and all the mechanism mounted thereon will rock forward or rearward accordingly, and this may be done so as to place the finger-bar at quite a considerable inclination during the operation of the machine if necessary to run over an obstruction or for cutting the stubble high or low. By the lever 90 the knife-bar is folded-that is, its outer end is elevated or depressed from a vertical upward position to about forty degrees depression from the vertical by the lever 90. The lever 90 is pivoted on the axle beside the plate 91 and has an end extending below the axle that is connected by a connecting-rod 92 with a crank 93 on the partial or mutilated 4the foregoing means does not interfere with the operation of the knife either during the alteration of the position or after the position of the finger-bar has been altered.

A plate 100 is secured on the upper side of the shoe 44 to furnish a guideway for the knife at the inner end, as appears in Fig. 3. As seen in Fig. 2, an adjustable sole 96 is made for the shoe 44, it being a plate secured at the front end by the bolt 97 and at its rear end having an upwardly-extending arm 98, with a series of holes therein, through which a pin 99 is inserted for securing it to the rear end of the shoe.
